DrTurbo built gt4088 Boxster "S" turbo for a client. This car is a limited edition model commemorating Porsches history. It is #095 of a total 1953 cars built worldwide.

Here's the limited edition badge; the photo didn't coome out too well!!

A nicely balanced and well-handling car; it lacks power and my client would often get blasted by $20,000 cars like the Srt-4, so we set about modifying it extensively

Please leave me a comment; and I'll be sure to return the favour!!

First time at the shop being fitted out with H&R springs.

Next step was to fabricate a custom Big Turbo kit. If we were going to do it, we were going to do it right, and BIG!

So I opted for a Garrett Gt4088 ATP turbo with a 1.14 A/R turbine and a Turbonetics Evolution 38mm wastegate. Then the real fun started - the build!

Here you can see the turbo and wastegate; they are mounted to the rear-side of the gearbox and the wastegate has it's own 40mm dump-pipe venting into the atmosphere.

The turbo has a 30cm long 3" diameter SS dump-pipe venting through the original slot in the rear bumper.

External oil reservoir before turbo oil-pump. This is to avoid excessively high oil-level within the turbo at shut-off; which would cause oil blow-by on the turbine and compressor housings.

3" 316-grade stainless steel dump-pipe, no silencers; what a noise this thing makes!

4" 316-grade stainless-steel turbo inlet tubing. It does a 180° bend up into the trunk to avoid dirt, water and grit.

Schedule 40 (3000psi) tubing for the 2-1 merge colector, which then heads back to the remote mounted turbo and wastegate.

Stainless Steel Tubowerx headers.

A general picture during build-up. These are the #316 Stainless Steel elbows that I use on all my builds, the Turbowerx external turbo oil-pump and the intercooler we used in this application; combined with Methanol injection.

This is a photo of another Boxster Turbo I built - with the intercooler in the trunk and ventilating fans underneath it. Also visible is the Blitz BOV and the 3" aluminium tubing- which goes through the fire-wall and directly to the throttle body.

The car ran extremely well; it really came alive with the boost pressure, but to take real advantage of that turbo and be able to get it into it's efficiency range I have decided to reduce Static Compression from around 11.3:1 to a much more boost-friendly 9:1

Once completed, it will be feasable to use up to 20psi of boost pressure and get the big GT40 really steaming.
